Fleet optimization to reduce CO2 emissions
Kolísek, Josef ; Jandová, Kristýna (referee) ; Bača, Petr (advisor)
This thesis deals with the issue of air pollution caused by the operation of cars. Nowadays, the topic of climate change, ecology of production, operation of cars and the related emissions they produce into the air is more and more trendy. This thesis focuses on the evaluation of the causes of exhaust emissions and their possible regulation and reduction. In the introduction of the thesis, the types of engines are classified according to their fuel and their various advantages and disadvantages. In the next part of the thesis, the attention is paid to the treatment of the real consumption values against the theoretical consumption values of hybrid cars, electric cars and conventional combustion engines. The thesis continues to analyze the time usage of different types of cars and their downtime in each quarter of the year and in this way evaluates the efficiency of different cars and the efficiency of battery usage in hybrid cars.

Energy data monitoring in electric vehicle
Krejz, Jan ; Dedek,, Jan (referee) ; Baxant, Petr (advisor)
The thesis deals with the monitoring of the energy data in an electric vehicle using modern diagnostics, using data readings from the CAN bus. The thesis can be divided into three parts. The first part provides a theoretical introduction to the measurement systems found in electric vehicles, then there are the methods of data transmission within the electric vehicle and the possibilities of how to obtain this data. The second part is an overview energy model that theoretically describes the possible flows of electrical energy within an electric vehicle, this theory is then supported by models in Simulink software for specific situations and tests where the theoretically calculated values of energy consumed were verified using this model. and the measured values. In the last section, a proposal for tests and locations where it would be appropriate to monitor these flows is presented. Some of the tests were performed and then evaluated.

Perspectives of hydrogen propulsion and electromobility
KLEIN, Jan
This thesis deals with the issue of hydrogen propulsion and electromobility. Initially, hydrogen as a chemical element is explained. Thereafter its production, transport and storage are described, the direct principle of hydrogen combustion is discussed and examples of cars using hydrogen are given. Then the subject turns to fuel cells, where the principle of its function is explained, several types of fuel cells are outlined, and the design of a fuel cell car is presented. Next, electricity and its infrastructure are highlighted, and the functional principles of electric vehicle components are explained. Then the functions and specifications of charging points are described. At the end of the theoretical part, different types of plugins for EV charging used globally are presented. In the practical part, an analysis of the number of hydrogen fuel cell cars and EVs worldwide, Europe and the Czech Republic was performed. Furthermore, the infrastructure of both types of cars was mapped on an identical scale and a survey was carried out in the district of Czech Budweis to map hydrogen filling stations and charging points for electric vehicles.

Ekonomická motivácia k nákupu elektromobilu v krajinách EÚ
Gogová, Patrícia
The diploma thesis examines the relationship between the number of electric vehicles in selected countries and economic incentives supporting the develop-ment of electromobility. Regression analysis is used to examine the relationship, the explained variable in the model is the number of electric cars in a given coun-try, the explanatory variables cover information about the infrastructure of charging stations, incentives, wealth and ecology of countries. The results indicate the impact of value added tax incentives and state contributions on the construc-tion of charging station infrastructure, and there is also a significant impact of the number of charging stations. In the cluster analysis, the formed clusters of states interpreted based on their similarities. The literature review examines the share of transport in greenhouse gas emissions, defines key concepts and principles of electromobility development.

Assessment of electromobility possibilities in the South Bohemian Region
DUCHOŇOVÁ, Eva
This diploma paper evaluates the possibilities of the current state and development of electromobility in the South Bohemian Region in connection to other alternative ways of transport using the knowledge and resources for the development of elec-tromobility worldwide and in the Czech Republic. It further describes the usage in countries whose development affects the electromobility and predicts future devel-opment in the Czech Republic. The possibility of using subsidy titles and state sup-port of electromobility in the Czech Republic is compared to the evaluation of local specifications influencing this development - demands on the distribution system, engineering requirements in the form of partial demands of charging stations (port-folio, service, etc.). At the same time, barriers and support for this life trend are indicated, including the assessment of the pros and cons concerning electric cars in the Czech Republic and in the South Bohemian Region using SWOT analysis and Porter's model. At the end of the paper to support my hypothesis there are used the results of a questionnaire survey among business and non-business residents of the South Bohemian region.

Přínos elektricky poháněných osobních automobilů pro snížení emisí oxidu uhličitého ve městech
VOTRUBA, Michaela Hana
Master's thesis deals with the issue of air pollution, to which automobile transport contri- butes extensively. Poor air quality has adverse effects on the health of every human being on Earth, so it is important to work constantly to reduce the emission footprint we leave behind. It is road transport that has a lot of room for improvement. The aim of thesis was to calculate the amount of CO2 produced by passenger cars on a selected section of the road in České Budějovice. And then calculate the amount of CO2, which would leave the same number of electric cars in the same driving section.

Rozbor faktorů omezujících rozvoj nízkoemisní mobility v ČR
BÍLÝ, Vojtěch
This bachelor thesis is focused on a negative influence which obstructs the low-emission mobility within the Czech Republic. In this thesis, various circumstances limiting the low-emission mobility are described. The electricity production is meant to be the crucial point here. Next, rather extensive part of the thesis deals with the legislation, and low-emission mobility support from the state. Then, the electromobile purchase cost is discussed. Thereafter, the electromobile range and its tests in winter are addressed. Also, a customer´s point of view is being referred to as well. In this thesis, the infrastructure of our country, electric recharging points construction, their types, and also plug-in types are described. As for the low-emission mobility, the ecology is of great importance. Related to this, the problems of carbon dioxide emissions as a part of electromobiles production, batteries production and recycling, and problems connected with electromobiles production, are discussed here. Safety standards are crucial here - an electromobile is quiet and it represents a higher risk of accident. Finally, the topic of hydrogen, as a source of a low-emission fuel, is also discussed. This thesis is based on a study of appropriate technical literature, specialized technical websites and non-fiction ones as well, and also it is based on hands-on experience with the electromobile of Škoda Citigoe iV.
